OK, with USB cable plugged into the PC the Windows version works. Next, to confirm, you did move the USB to the Pi? Did you reboot the Pi after plugging in the USB? Not just restart FRStack. From the

After much machinations, I've got my node up and talking with my 6400 and FRStack, hand have configured the FRStack to the amp's USB serial port. (in my instance I have linked /dev/ttyUSB_AMP to
